Ok, I turned on namespace processing using setDoNamespace(true), but the
results are not what I expected (see below). I want to use an external
schema specified by the caller and not the schema called out in the XML
document. How do I do this with Xerces? And what exactly is the cause of
the below error?

Parser Error Message: The schemaLocation attribute does not contain

You used
_XmlDOMParser->setExternalSchemaLocation((const char* const)schema);
that requires a string like "uri schema uri2 schema2" (i.e. "pairs of
values") where 'schema' is the location of the schema for the namespace
'uri' and 'schema2' is the location of the schema for the namespace 'uri2'.
In your case the schema is for the empty namespace, so you must use
setExternalNoNamespaceSchemaLocation

You also need to turn on namespace processing using
setDoNamespaces(true)

Hello,
I trying for the first time to validate an XML document with a schema,
but I'm not sure of the results from the parser. I'm currently using
Xerces C++ 2.8.0 DOM Parser. What is the correct syntax to specify a
schema? If the schema and xml file are in the same directory can I
just use the filename of the schema or do I have to specify a full
pathname?
If the schema is not in the same directory or location then what is
the correct syntax? Here's what I've done.
Code snippet:
==========================================================
//perform the necessary DOM Parser init and setup ... omitting all the
gory details
//setup the Entity Resolver to redirect the parser to use the external
Schema _XmlDOMParser->setEntityResolver(resolver);
//Turn on the necessary features to allow validation by an external
Schema _XmlDOMParser->setValidationScheme(_XmlDOMParser->Val_Always);
//enable schema processing
_XmlDOMParser->setDoSchema(true);
//specify schema to use where scheme syntax is the filename i.e
bcme.xsd _XmlDOMParser->setExternalSchemaLocation((const char*
const)schema); _XmlDOMParser->loadGrammar(schema,
Grammar::SchemaGrammarType, true);
//ignore DTD's
_XmlDOMParser->setSkipDTDValidation(false);
//attempt to parse the xml
_XmlDOMParser->parse(xmlDoc2Parse);
